Classic romaine, modern reliability for your salads

The Parris Island Cos variety from Survival Garden Seeds brings a familiar crunch and a mild, refreshing bite to every bowl. Expect tall, crisp green heads with tender hearts that make Caesar salads and everyday greens feel special.

Designed for diverse garden conditions, this romaine is heat tolerant and slow to bolt, especially with steady watering and partial shade. In warm seasons it can maintain steady growth, giving you a dependable harvest window even in warmer climates.

Germination and growth shine across cool or warm climates, thriving in USDA Zones 3 through 9. It adapts to garden beds, raised planters, and even containers, so you can cultivate fresh greens in small spaces or larger plots. Year-round planting is possible, with open-pollinated heirloom seeds that remain true to type season after season. You can also grow indoors for consistent access to crisp salads, and storing extras in your seed vault keeps a backup on hand.
